Note: The U.S. Environmental Protection agency requires manufacturers to provide a Noise Reduction Rating (NRR) on all hearing protection type products being marketed into most commercial type accounts. According to E.P.A. Document 08AR-2003-0024, exception to this requirement may be granted to entities participating in National Security. OSHA regulations state volume levels of 80-85 dB are safe for an eight hour period of time.
Please consult a hearing healthcare professional who can advise you about safety levels and appropriate filtering options.
